VALVE-,REGITLATOR Specification of Letters Patent. Patented NOV, 16 1915;

Application filed'December 13,1913.- Seria1No.806,552.

Toall whom it may concern 1 Be it known that we, LEON Gnonen M. STAINS, citizensof the United States, residing at Youngstown and Cleveland, respectively, in the counties of Mahonfull, clear, and'exact description ofthe invention, such as will enable others skilled in the art to which it; appertains to make and l p her and a floatfor operating the valve.

improveerates without awaste of steam or water,

which is unaffected by temperature andpressure changes;a'ndwhich is of extremely simple and practical construction, having no needle valve, dlaphragm, expansion elements and the like.

Another and more specific ohject ofthe invention is to provide ayregulator of this type having a float which operates a slide valve, the latter servingto release the pressure from one sideorthe other of a piston or plunger which is operatively connected to" the feed" water valve.

As a further object, the invention contemplates the provision of a'valve regulator which shall be a general improvement over devices of a similar nature now in use.

With these and other objects in view as will become more apparent as the. description proceeds, the invention consists 1n cer ta1n novel features of construction, combination and arrangement of parts as willbe more" fully described and" hereinafter claimed. c

For a complete understan'dlng-ofi our invention, reference is to be had to the follow-' ing description andaccompanying' drawings, in which I Figurel is a vertical sectional View thereof being shown in elevation,Fig.,"21is fragmentary- -detail* sectional view'partly in I elevation, showing the float, slide valve cas T. MART and ing, slide valve and cooperating parts, and

Fig. 3 is-"a view showing'in elevation a see I tion ofthe feed wa'ter'pipe, feed valve and valve lever.

Generally. considered, the invention c'omprises float chamber, a plunger or piston cylinder; a'piston'or plungeroperablewithin said cylinder, pipes connected to the piston and extending into the float chamber, valve inechanismifor controlling the flow of water from the cylinder to the float cham- Taking up. the parts in the order named,

5 designates, asfan entirety, a cylindrical casing forrnlng the float chamber 6 and com-T prising a body 7, a top wall 8 and a head 9 which closes the lower open end of the body.

level within the float chamber corresponds to the level within theboiler. The head 9 is preferably connected t'ozthe casing 5' by the cap screws 14.

Passing now to the piston or plunger cyl inder 15, we see that it consists of a body 16 andheadefl and 18; The head 17 is integrally connected to the head 9'by the arms 19' and has its inner'or lower face centrally recessed, as indicated by the numeral 20and threaded toreceive the upper threaded terminal of the body 16. The head 18', which closes the lower end of the "body 16, is

formed with an internally threaded periph eral flange 21 which engages the threaded exterior ofthe body. Each ofthe heads 17 and 18 is formed wit-h an angular port or bore 22 which opens upon the periphery of the head and upon the inner face thereof Witliin'the body 16. Pipes-23 and 24 conmet the bores ,22 withthe feed water pipe 25in advance of the feed water valve 26.

Takingupjajs next in order the plunger or piston 27, which operates withintlie cylinder 15', we seethat it is formed with a central longitudinal bore 28', the upper end of which: opens upon a chamber or recess 29off a greater diameterth'anthe' bore; Thepiston ing lever 31.

is preferably cast integrally with a stem or rod 30 which extends through the head 18 and which: is connected to: the valve operate, Ports 30 are formed in the piston rod 30 adjacent the piston 27 and" establish communication with the interior of the cylinder15 andthe'bore 28.

Aspipe 32 is threaded at its lower end into therecess 29 and extendsnpwardly through'the heads 17 and 9 into the'float chamber '6 'llhisfpipev is formed-adjacent its lower end with a port 33 to establish com munication betweentheinterior of the ,cyl-i inder and the interior of the pipe 32. A

the pipes32and 34 into the float chamber 6, includes ajvalve. casing .35 formed in its lower end with a chamber 36 into which second pipe 34 is threaded. into the upper end ofthe bore, 28 and extends through the 1 pipe- 32 in spaced relation to the interior I thereon} x c The means provided for controlling the flow of water from the cylinder 15 through the upper terminal of the, pipe 32 isthreaded, as clearly, shown in Fig.2. .The pipe 34 abuts the/.1 01 of therecess36, and is alined with a longitudinal; bore 37 extend- 1 ing through the casing 35 and communicatbore 38 and at its lower endwith the charm ing at its upper 'end with a transversebore orpassage 38. 'The casing is also formed 1 with a longitudinal bore 39 which communicates at its upper end with the transverse ber 36 between the pipes 32 and 34. .A slide valve 40 operates transversely of the casing.

35 and is formed with a passage 41 which registers with the bores 37 and 39.

A-saucer shaped shield 41 is formed integrally with the valve casing 35 and besides serving to prevent an undue agitation of the water within the float chamber 6, provides a support 42 for the pivoted float arm This arm is pivoted at one end to the support 42 and'has. attached to its other end a float 44which is positioned directly over the shield 41. A rod 45 is pivotally connected at its upper end to the arm 43,

extends downwardly through an opening 46 formed in the shield andis connected at its lower end to one arm of a 'bellcrank lever 47. This lever is pivoted to a laterally projecting stem 48 carried by the casing 35 and is connected to theslide valve 40.

Having described the construction of the feed water valve regulator, 1t now remains to explain the operation thereof and in order to simplify this portion of the description,

\ we will assume that the device is used to.

1 6O regulate the water level within a boiler.

The casing 5 is mounted so as to extend above and below the water level in the boiler and as before stated the pipes 12 and 13 are connected to the boiler above and belowthe water level respectively. The piston rod30 .55 'is connected to thelever 31 of thefeed valve 3 .feed water pipe .25.

' unaffected by; temperature '26 and the. pipes 23 and 24 are connected ;to a pipe 49 which is communicant with the lVith the w ater at i the desired level within the boiler, the plunger Irod -30Iis connected to the lever 31 so 'that when the float 44 is properly supported by the water in the float chamber 6, the valve 26 will be set so. as to allow the desired amount of water to feed into the boiler, to

compensate for thenormal loss 'ofwater by,

using the I steam generated. The pressure of the feedwater is maintained at a greaterdegree than the boiler Y pressure,1 and the ports of the valve casing 35 are designed to.

allow water to flow more, rapidly'into the 8O float chamber 6 than it entersthe-cylinder.

15;through the bores or ports 22. With- 7 these observations in mind, it will be seen that arise of wate level within the boiler will lift the float 44, causing the passage 41 of the slide valve to .regi ster with the I passage 39 in the casing 35, at which time cylinder '15,, through the pipe 32 into the float chamber 6, and since water may exhaust from the, cylinder 15 morerapidly than-it may flow thereinto, it is evident thatv the pressure upon the top o fthe piston 27will be reduced. The piston will then raise the float to the new level and reducethe volume of water flowing through the valve 26. 3

Should the'water level continue tov rise, the

water will flow from-the upper end of thev 7 plunger 27 will again-move upwardly. until the valve 26 is entirely closed. 1 When the water level within the boiler drops, the float drops and actuates the slidevalve 40 to bring its port 41 into registration with they passage 37. at which time water will exhaust or flow from the lower side of the will be further opened to allow a more rapid flow of water into the boiler. Each movementlof the piston 27 readjusts the position of the float withrespect tothe'water level in thefloat chamber so that the'float re- 7 mains. normally supported entirely by J the water within the float chamber, at which time the valve 40is closed. 1

From the foregoing description taken in connection with the accompanying drawings, it will be seen that we have provided a very simple, practical and substantialfeed water valve regulator, which is verysensitive to changes-of water level; which is devoid of intricate mechanism; which is or pressure changes; and which operates without a waste j of steam. or water.

;While,we have shown and described the ilac.
